The 350-year-old Rongbaozhai is a company dedicated to the traditional Chinese culture. From a southern paper store established in the 11th year of Emperor Kangxi's reign in Qing Dynasty to a time-honored brand for the Four Treasures of the Study, painting & calligraphic works, and intangible cultural heritage items, Rongbaozhai has undergone too many rises and falls and created too many wonders in the past three and a half centuries. Its ace in the hole is the operation philosophy, which has been the pursuit of an immeasurable number of men of accountability and curiosity. This book endeavors to unravel the secrets by recalling and exploring from all angles.
